The Montblanc 310 is a slim, fountain pen from Montblanc’s 1970s 3xx series, maintaining Montblanc’s clean, functional aesthetic. The pen features a lightweight resin body, a simple straight-lined silhouette, and a steel nib engineered for reliable everyday writing. It uses standard international cartridges and reflects Montblanc’s focus during the era on practical, modernist design. The pen is in excellent, pre-owned condition and has been carefully cleaned. Imperfections: light scratches. The pen is supplied with two ink cartridges. A converter is not included.
